How To Use An Email Validator Online?

Did you know that as much as 20% of addresses on the average email list are invalid, containing typos, syntax issues, and other errors?

That may not sound like a big deal… until you realize that every time you send to these addresses (as well as other malicious addresses that could be on your list, like spam traps, bots, and complainers), you are harming your sender reputation and increasing the likelihood that your future emails will end up in the spam folder.

Fortunately, there’s an easy, “one-click” way to rid your list of these invalid and dangerous emails, and that’s by using an email validator.

Keep reading to discover what an email validator is, the immediate benefits of using one, and how you try out an email validator online free for your own business today.

What Is an Email Validator?

In short, an email validator is a tool that uses pre-set and real-time rules to verify that each of the email addresses on your list is valid and not dangerous.

This tool is browser-based, which means you don’t have to download any bulky software to use it. Simply register at the website of the email validator that you want to use and then follow the instructions we’ve laid out below to clean your list.

What Are the Benefits of Using an Email Validator?

There are a few key benefits that make using an email validator in your business a no-brainer.

Here are the three big ones:

1. Increase Your Deliverability Rate

By removing the invalid emails on your list, an email validator can help you instantly increase your email deliverability rate.

This is important because every time you send an email to an invalid address, that email will bounce.

This puts you in hot water because having a high bounce rate is a red flag for email service providers who will likely penalize your sender reputation and doom your future emails to the spam folder.

Sending emails to malicious addresses such as spam traps, bots, and complainers will also harm your sender reputation, which means it’s crucial that you use an email validator online to clean these harmful addresses off your list.

2. Save Money

Sending emails to a list is expensive.

If you own a large list, it can cost hundreds to thousands of dollars every month in service and sending costs.

Fortunately, using an email validator can instantly reduce this cost burden by:

  • Boosting the ROI of your email campaigns thanks to a higher deliverability rate that enables you to reach more of your subscribers’ inboxes
  • Directly reducing your service and sending costs by removing invalid and dangerous emails
3. Get Better Insights

Having accurate customer and prospect data is crucial for any business.

When you use an email validator to clean bad data off your list, the insights you receive after running email campaigns become more accurate.

These insights will help you make better business decisions.
